# Interface: com.pnfsoftware.jeb.core.units.code.android.IAndroidEmulationHooks

Interface for plugins that provide hooks for the emulation of dex code and native code. 

 At this time, those plugins can be [used](#getUsage()) by the [APK generic unpacker ](IGenericUnpacker). They are not used by IR optimizers using the emulator. \(Future addition.\) 

 Implementors should not implement this interface directly: extend [AndroidEmulationHooksSkeleton](AndroidEmulationHooksSkeleton) instead.
